Manipulative mothers and family feuds: evolution of maternal effects under mother-offspring conflict. Can mothers shape the lives of their offspring and their grand-offspring? Can siblings shape the lives of their brothers and sisters? This project will address how mother and offspring strategies affect current and future generations. This is crucial for understanding how mothers will direct and accelerate evolutionary change in our changing world.

Understanding the relationship between the social environment and cognition. The predominant theory for the evolution of intelligence, the social intelligence hypothesis (SIH), posits that within-group social interactions drive cognitive evolution. But the SIH overlooks a major component of social life: interactions with outsiders of the same species. Using a unique combination of meta-analytical and experimental approaches, the DECRA project will test the predictions of an expanded SIH, incorpo ....Understanding the relationship between the social environment and cognition. The predominant theory for the evolution of intelligence, the social intelligence hypothesis (SIH), posits that within-group social interactions drive cognitive evolution. But the SIH overlooks a major component of social life: interactions with outsiders of the same species. Using a unique combination of meta-analytical and experimental approaches, the DECRA project will test the predictions of an expanded SIH, incorporating the “Napoleonic” cognitive challenges posed by outsiders. The expected outcome is to gain a new understanding of which factors govern cognitive evolution – one of the longest-running debates in evolutionary biology.Read moreRead less
Understanding the survival of forests under drought . Droughts are predicted to become more extreme in the near future, with potentially devastating impacts on Australian forest ecosystems. This project aims to address key knowledge gaps in our understanding of how plants tolerate extreme drought stress and utilise this new knowledge to improve vegetation models suitable for assessing ecosystem vulnerability. We will use innovative experimental methodology to determine the processes by which wat ....Understanding the survival of forests under drought . Droughts are predicted to become more extreme in the near future, with potentially devastating impacts on Australian forest ecosystems. This project aims to address key knowledge gaps in our understanding of how plants tolerate extreme drought stress and utilise this new knowledge to improve vegetation models suitable for assessing ecosystem vulnerability. We will use innovative experimental methodology to determine the processes by which water transport breaks down in roots, stems and leaves and the mechanisms governing recovery from severe drought stress. The project will provide a deeper understanding of drought tolerance in trees, improved forecasting of risks to native vegetation, and enhanced management of native forest resources.

Transgenerational Consequences of Different Environmental Experiences. The project aims to deliver an integrative overview of behavioural, evolutionary and environmental epigenetics. In particular, by studying why stress-related experiences of organisms (e.g. exposure to toxins) can be passed onto the future generations regardless of its seemingly fitness-reducing impacts. It also aims to test if the seemingly beneficial effect of non-stress related experiences (e.g. environmental enrichment) ca ....Transgenerational Consequences of Different Environmental Experiences. The project aims to deliver an integrative overview of behavioural, evolutionary and environmental epigenetics. In particular, by studying why stress-related experiences of organisms (e.g. exposure to toxins) can be passed onto the future generations regardless of its seemingly fitness-reducing impacts. It also aims to test if the seemingly beneficial effect of non-stress related experiences (e.g. environmental enrichment) can be inherited transgenerationally. This project involves both research synthesis (e.g. meta-analysis) and experiments on zebrafish employing cutting-edge statistical, computational and molecular methods along with behavioural assays. Also, the outcomes of the synthesis are expected to guide future work in the field. Read moreRead less
Sex chromosomes and speciation: chromosome inversion and the large Z-effect. This project aims to understand the divergence of species and the importance of two genomic features of often disproportionately large effect between young taxa – the sex chromosomes, and chromosome inversions. The research will integrate genomics and transcriptomics with the study of traits closely aligned to speciation in birds – song, colour, and sperm morphology and protein composition. The project will provide sign ....Sex chromosomes and speciation: chromosome inversion and the large Z-effect.

The research will integrate genomics and transcriptomics with the study of traits closely aligned to speciation in birds – song, colour, and sperm morphology and protein composition. The project will provide significant benefits such as enhancing Australia’s strength in the field of evolutionary biology.Read moreRead less
Plastic pollution: new driver altering responses to variable environments. This project aims to determine how bisphenol A (BPA), which now represents a novel environmental driver, alters physiological responses of animals, and how it interacts with other environmental variables to alter ecological and evolutionary trajectories. Plastic pollution is a monumental global environmental and health problem, and Australia has one of the world’s highest exposures to BPA, a plastics leachate. This projec ....Plastic pollution: new driver altering responses to variable environments. This project aims to determine how bisphenol A (BPA), which now represents a novel environmental driver, alters physiological responses of animals, and how it interacts with other environmental variables to alter ecological and evolutionary trajectories. Plastic pollution is a monumental global environmental and health problem, and Australia has one of the world’s highest exposures to BPA, a plastics leachate. This project will use a new zebrafish gene knock-out model to show whether the effects of BPA are transferred between generations, and will establish an international collaboration, thereby increasing Australia's research capacity. Outcomes from the project are expected to benefit environmental management.Read moreRead less

Mechanisms influencing the evolutionary trajectories of extended phenotypes. Although we know how the environment and predator-prey interactions shape traits, we have a poor grasp of the evolution of extended phenotypes. The webs of spiders have switched repeatedly between two- and three-dimensional forms over time, so are excellent models for assessing extended phenotype evolution. This project will use innovative experiments to assess whether the prey capture performance of webs or their visib ....Mechanisms influencing the evolutionary trajectories of extended phenotypes.

Integrating biomechanics and ecology: moving from an individual- to population-level understanding of the effects of environmental change. Coral reefs, a key Australian resource, face an uncertain future due to environmental change. Up to now, environmental change research has focused on the individual level, severely limiting our predictive capacity. This project will develop a novel 'first principle' approach to solve this shortcoming and make population-level predictions possible.
From individual interactions to global patterns: understanding the basis of collective behaviour. Some of the most incredible sights in nature happen when animals form into groups, such as shoals or flocks. This study examines the phenomenon of collective animal behaviour to understand how simple interactions between group members scale to produce these behavioural spectacles.
The effect of native invasions on Australian fisheries species. This project aims to forecast climate-related changes in the diversity, distribution and abundance of fisheries species. In a changing world where many people depend on oceans for food and livelihood, predicting the future distribution of fisheries species is a challenge. Native invasions and ocean warming are stressing inshore fisheries species, but rigorous empirical data and models that can reliably forecast these effects are lac ....The effect of native invasions on Australian fisheries species. This project aims to forecast climate-related changes in the diversity, distribution and abundance of fisheries species. In a changing world where many people depend on oceans for food and livelihood, predicting the future distribution of fisheries species is a challenge. Native invasions and ocean warming are stressing inshore fisheries species, but rigorous empirical data and models that can reliably forecast these effects are lacking. This project intends to reveal the drivers of successful native invasions, evaluate their effect on fish diversity and productivity, and develop holistic models that forecast their effects on inshore fisheries species’ near-future distribution and stocks.Read moreRead less
